Ratings and reviews

Great calculator. I use it all the time, it has a proper intuitive "old school" input unlike most horrible hardware calculators nowadays which do stuff backwards. Don't miss the three little dots for "settings", I missed that at first, and there is some useful stuff in there. (.. For example tuning vibra makes it more snappy, and chance to reverse some of the shift key functions).

Great app. Been using the free version of this quite happily for some years. Not sure if still being supported but decided to upgrade nonetheless (mostly to thank the developer for a job well done). "If it ain't bust don't fix it" - Quartic Software, if you're reading this, please don't make any significant changes. This app does what it says on the box and is all the better for it.

I have used the free version of this on every Android phone I have owned. It provides more than enough features to replace my desk scientific calculator. Having just brought an S6lite tablet was pleased to see it works perfectly in both landscape and portrait and decided to upgrade to pro paid version. Well worth the few quid to have an excellent calculator on all my devices for less than replacing my old desktop one.
